Struct WriteConcernOptions 

pub struct WriteConcernOptions { /* private fields */ }

Per-write wait policy. Timeout starts when the receiving node applies the update. Transport and actor admission have their own deadlines.

Implementations

impl WriteConcernOptions

pub fn builder() -> WriteConcernOptionsBuilder

Create an instance of WriteConcernOptions using the builder syntax

impl WriteConcernOptions

pub fn minimum_durability(&self) -> WriteDurability

pub fn with_minimum_durability(self, durability: WriteDurability) -> Self

pub fn require_evidence(&self) -> bool

pub fn with_require_evidence(self, required: bool) -> Self

pub fn concern(&self) -> WriteConcern

pub fn timeout(&self) -> Duration

pub fn require_other_region(&self) -> bool

Whether success additionally requires a processed outside-region replica.

pub fn with_require_other_region(self, required: bool) -> Self

Add or clear the independent region acknowledgement requirement.

pub fn strict_acknowledgements(&self) -> bool

Whether an operational cap must preserve the requested count. This does not change the configured storage durability or LWW winner semantics.

pub fn with_strict_acknowledgements(self, strict: bool) -> Self

Require or relax preservation of the requested acknowledgement count. Older peers reject an enabled constraint before applying the mutation.

pub fn validate(&self) -> Result<(), WriteConcernPolicyError>

pub fn encode(&self) -> Result<Vec<u8>, WriteConcernPolicyError>

pub fn decode(bytes: &[u8]) -> Result<Self, WriteConcernPolicyError>

Unknown policy fields are rejected, so an older implementation cannot silently ignore a new required acknowledgement constraint.
